Question

2 — causes of climate change
learning objective: determine the causes of climate change.
carbon dioxide and methane are two of the worst greenhouse gases.
which of the following statements is true of methane?
a.) current agricultural practices increase the amount of this gas.
b.) burning fossil fuels is the human activity that is the primary source of this gas.
c.) deforestation has reduced the amount of this gas that can be absorbed.
d.) this is the greenhouse gas that humans produce in the largest volume.

Explanation:

Methane is produced in agriculture through processes like livestock digestion and rice - paddy cultivation. Burning fossil fuels mainly releases carbon - dioxide. Deforestation affects carbon - dioxide absorption more directly as trees take in carbon - dioxide. Carbon - dioxide is the most abundantly produced greenhouse gas by humans.

Answer:

A. Current agricultural practices increase the amount of this gas.
